SAE J2691:2020 pdf free.15 Pole Connector Between Towing Vehicles and Trailers with 12 Volt Nominal Supply
This SAE Standard establishes the minimum construction and performance requirements for a 15 pole connector between towing vehicles and trailers, for trucks, trailers, and dollies, for 12 VDC nominal applications in conjunction with SAE J2742.The connector accommodates both power and ISO 11992-1 signal circuits along with dual ground wires to accommodate grounding requirements within the constraints of the SAE J2691 terminal capacity.
The following publications form a part of this specification to the extent specified herein. Unless otherwise indicated, the latest issue of SAE publications shall apply.
The SAE J2691 connector and SAE J2247 cable designs contain a primary and secondary ground circuit. The combined CMAs of these primary and secondary ground circuits are greater than the CMA of the single ground currently found in the SAE J560 connector and SAE J2394 cable but independently neither the primary or secondary ground of the SAE J2691 or SAE J2742 will equal the one ground circuit found in the SAE J560 and SAE J2394. Therefore, it is imperative both tractor and trailer OEs that employ the SAE J2691 and SAE J2742 standards create a common parallel ground bond between terminals 1 and 8 of the SAE J2691 connector within their respective wiring architecture.
